Turbulence convective numerical scheme poor default

[WallyMaier]

When running a turbulence model, one must select CONV_NUM_SCHEME= SCALAR_UPWIND.
To my knowledge, this is the only option to run RANS.

In my opinion, this should should be defaulted to the option that would allow this to run.

I think this brings up a bigger issue, that I have mentioned before, it seems that options and defaults are mismatched, poor or not properly documented.

Are there defaults for convective schemes? Looking at the code that does not seem to be the case.

[WallyMaier]

You are correct. However this leads to weird behavior when running.

As much as bug reports and enhancements are also appreciated, we are not following the strict see something, say something policy :) we need more application of the see something, do something policy :D

Addressed in #824, error message thrown (it is not easy to implement a good default due to shared code with other CONV_NUM_METHOD_??? options).
